ratio is constant for all angles of incidence when light passes fromwater to air. Explanation of refraction. — When light passes from onemedium to another of different density, the curvature of thewave fronts is altered, because the light travels at a differentvelocity in the second medium. Since… … FIG. 184. — Light passing from waterinto air. We may illustrate this by an example. It is known that light travels faster in air than in water, and when we view an object in water, the light moves from the object to the eye, first through water and then through air. When a wave front reaches the…
